ROLLER-BEARING.

SPECIFICATION forming part of Letters Patent No. 633,053, datedSeptember 12, 1899.

Application filed June 6, 1899.

"0 (all (If/tent it 7mg concern.-

.lEe it known that I, PHILIP M. LOUIS, of Carmel, in the county of\Vaupaca and State of lVisconsin, have invented a new and ImprovedRoller-Bearing, of which the fol lowing is a full, clear, and exactdescription.

The object of the invention is to provide a new and improvedroller-bearing designed for use on shafts, bicycles, and other machinesand devices and which is simple and durable in construction and arrangedto reduce the friction to-a minimum.

The invention consists of novel features and parts and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claims.

A practical embodiment of my invention is represented in theaccompanying drawings, forming apart of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a cross-section of the improvement as applied on a shaft.Fig. 2 is a sectional side elevation of the same on the line 2 2 in Fig.1, and Fig. 3 is a cross-section of the improvement as applied to abicyclewheel and with the rollers on one side of the hub removed.

The improved device illustrated in Figs. 1 and 2 is applied on a shaftor spindle A,forn1ed with a bearing-ring B, engaged at its inner surfaceby a set of rollers O and at its outer peripheral surface by another setof rollers D, said rollers having heads or flanges C D in contact witheach other, as is plainly indicated in Fig. 2,so as to keep the rollersin each set spaced the desired distance apart. The inner set of rollersC also engages a track E, formed or secured on a casing F, and the outerset of rollers D engages a track Gr, likewise formed or secured on thecasing F and concentric with the shaft A, the track'E, and thebearing-ring B. Now it will be seen that when the shaftA is rotated thesets of rollers O and D by being in contact with the inner and outersurfaces of the bearing-ring B, which revolves with the shaft, arecaused to rotate in opposite directions and rollupon the fixed tracks Eand G of the casing F. As the rollers are in contact with each other bytheir flanges or heads, it is evident that they rotate in unison, and atthe same time the rollers in Serial No. 719,572. (No model.)

a set are kept apart from one another, thus preventing undue frictionand insuring an easy running of the shaft A.

In the arrangement shown in Fig. 3 the sets of rollers C D engage theinner and outer faces,respecti vely,of a bearing-ring B,forn1cd orsecured on a cap B, attached to the hub A of a bicycle-wheel. The innertrack E is secured to an axle II, carried by the forks I of thebicycle-frame, and on said axle is also secured an outer track G, aswill be readily understood by reference to Fig. The operation of thisdevice is exactly the same as the one above described in reference toFigs. 1 and 2.

As indicated in both Figs. 1 and 3, I prefer to make the innermost trackE orE somewhat wider than the outermost track G or G and thebearing-ring B or B, so that the heads of the rollers are not liable tocome in contact with the outer edge of the bearing-ring B, therebypreventing undue friction at this point.

From the foregoing it is evident that by having the sets of rollersarranged as described the bearing-ring is between two sets ofbearing-rollers, thus forming double bearingsurfaces sustaining the loadequally. When in use, the load bears against the outer set of rollers atthe bottom while it bears against the inner set at the top, thusrendering the bearing frictionless as faras Vertical strain isconcerned.

The arrangement described forms a very simple and durableroller-bearing, not liable to get out of order or become disarranged andbind when in use, and for light machinery the rollers can be made hollowto reduce the weight of the bearing to a minimum.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. A roller-bearing, comprising concentrictracks having a common support, an intermediate bearing-ring, and setsof rollers, one set between the inner track and the inner face of thebearing-ring and the other setbetween the outer track and the outer faceof the bearing-ring, and means upon each set of rollers for keeping therollers of the other set spaced apart or out of contact, substantiallyasshown and described.

2. A roller-bearing, comprising concentric tracks, an intermediatebearing-ring, and sets of rollers, one set between the inner track andthe inner face of the bearing-ring and the other set between the outertrack and the outer face of the bearing-ring, each of the rollers beingprovided with a head or flange, the flanges of the inner and outer setsof the rollers being in rolling contact with each other, to keep therollers in each set spaced apart, substantially as shown and described.

3. A roller-bearing, comprising fixed concentric tracks, a revolublebearing-ring in substantially the same planes with and intermediate saidtracks, a set of rollers between the inner track and the inner face ofsaid bearing-ring, and a second set of rollers between the outer trackand the outer face of said ring, substantially as shown and described.

4;. A roller-bearing, comprising fixed con centric tracks, a revolublebearing-ring in substantially the same planes with and intermediate saidtracks, a set of rollers between the inner track and the inner face ofsaid bearing-ring, a second set of rollers between the outer track andthe outer face of said ring, and annular flanges on said rollers, theflanges on one set of rollers being in frictional contact with theflanges on the other set of rollers, substantially as shown anddescribed.

5. A roller-bearing, comprising concentric tracks and an intermediatebearing-ring, the tracks and bearing-ring being located one on thestationary member of the bearing and the other upon the rotat-in gmember, and two sets of rollers lying between the bearing-ring and theconcentric tracks and in contact therewith, substantially as described.

6. A roller-bearing, comprising concentric 4o tracks and an intermediatering,'the tracks and bearing-ring being located one on the stationarymember of the bearing and-the other upon the rotating member, two setsof rollers lying bet-ween the bearing-ring and the con .5 centric tracksand in contact therewith, said rollers having flanges upon one endoverlaplaping the bearing-ring, and the flanges of one set havingrolling contact with the flanges of the other set, substantially asdescribed.

7. A roller-bearing, comprising concentric tracks and an intermediatebearing-ring, the tracks and bearing-ring being located one on thestationary member of the bearing and the other upon the rotating member,two sets of 55 rollers lying between the bearing-ring and the concentrictracks and in contact therewith, said rollers having flanges upon oneend overlapping the beari11gring,and the flanges of one set havingrolling contact with the flanges of 60 the other set, the concentrictracks having grooves alongside their bearing-surfaces and accommodatingthe roller-flanges without con tacting with the peripheries thereof,substan- Y tially as described.
